Description

C202CR3 is a JGS1 quartz large-window cuvette for UV/Vis spectroscopy with a 20 mm optical path and 34.4 mL nominal capacity. This version combines a larger upright chamber with an open-top body, giving you direct access for filling, rinsing and visual inspection when your method already allows a higher sample volume.

Choose this option

Choose this cuvette when you need a 20 mm transmission path in a larger-format sample cell rather than a compact routine footprint. The listed internal dimensions of 43 × 20 × 50 mm make the chamber size and body clearance easier to plan together, especially where sample loading from the top is preferred.

What makes this option different

20 mm optical path for UV/Vis methods specified around a longer transmission length.
34.4 mL nominal capacity in a large upright chamber rather than a small-volume format.
Open-top body for direct pipetting, pouring, rinsing and visual checking before measurement.
Two-Way Light layout for measurement through two opposing optical faces.

Using this cell

Fill the cell from the open top, then check that the liquid fully covers the measurement region and that the optical faces are free from bubbles, droplets and residue. The larger chamber is useful when your procedure accepts a higher fill volume and you want straightforward top access during loading and cleaning.

Handle the cuvette by non-optical surfaces where possible to keep fingerprints away from the light path. This listing does not establish a supplied closure, so plan on open-top use unless you have separately confirmed another arrangement.

First-use check

Inspect the chamber and optical faces on receipt, rinse the cuvette appropriately for your method, and verify that it seats securely in the holder. Before sample runs, use your normal blank and confirm that the illuminated region remains fully covered by liquid during measurement.

Fit and optical alignment

The uncapped body dimensions are 47 × 24 × 52 mm, with internal dimensions listed as 43 × 20 × 50 mm. Check holder width, depth and vertical clearance before ordering, as this is a larger upright cuvette body.

Z Height is not listed for this SKU. If your holder or spectrometer requires a defined beam-center height, confirm that requirement separately instead of assuming fit from overall size or path length alone.

Solvents and cleaning

This cuvette is made from quartz for UV/Vis use across the stated wavelength range. General background on MQ cuvette fabrication options is available here: Compare fabrication methods.

Do not use hydrofluoric acid on quartz. Avoid hot strong alkalis and abrasive cleaning. Chemical limits for this exact assembly are not separately listed here, so review compatibility before use if your sample or cleaning routine involves more aggressive conditions.

Included with this option

1 cuvette per listed price unit. If you need a supplied closure or other accessory, contact us before ordering.

Availability and ordering

Order this specification directly, or contact us to check current availability and dispatch timing. If temporarily unavailable, additional preparation or production time may be needed. For a required delivery date, contact us before checkout; preparation or production is separate from carrier transit and customs clearance.

Discuss a custom version

We can review custom JGS1 quartz projects involving dimensions, optical path length, sample volume, optical windows or Z Height, closures and connections, and tolerance requirements. Send a dimensioned drawing or labelled sketch, together with holder details and sample conditions, and discuss your requirements with us.
